When you unbolt the dipstick tube,you'll run into it,and know which bolt we're talking about,lol. It's the bottom bolt /bracket down towards the oilpan.On a 4X4 it's usually to long to actually remove,so you're either faced with cutting the bracket or the bolt. If you have a small angled air die grinder and a slim zip /cut-off disc you should be able to back the bolt out till it won't back out anymore,pry the dipstick/bracket out as far as you can,then get in behind the bracket with the cut-off disc and cut the bolt,pull it out and clean up the end of it on a bench grinder and you should be able to re-use it. The other option is cut the bracket off the dipstick and don't worry about it,lol
